PHOTOGRAPHIC PRINTER.

Application led .Tune 28, 1921. Serial No. 481,071,

T 0 all whomy t may concern.:

Be it known that I, 'JULIAN A. dArisnY, a citizen of the United States, residing at VVa-sliington, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Photographic Printers, of which the follow- @ring is a. full, clear, and concise description thereof.

One object of the invention is to provide a power-operated photographic printer,each movement of which is under the voluntary control of the operator. Another object of the invention is to provide a printer, the working forces for which are supplied by a source of power instead of by the operator, thereby relieving the latter from fatigue and increasing the output, each movement of the printer taking place upon a simple actuation of a control means by the operator. Still another pbje'ct 'of the invention is to provide a printer of this character which is fluid operated. A further object of the inventionis to include in the printer means for storing energy in a simple manner, so that the operator can release the energy at will to move the platen. Another object of the invention is to automatically time the operations of a light and of a. paper-ejector in a printer of this character.

Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevation of the printer.

Figure 2 is a longitudinal section through the cylinder thereof.

Figure 3 is a longitudinal section through the valve.

Figure 4 is a front elevation of the entire device.

Figure 5 is a horizontal section through the upper portion of Fig. 1.

Figure 6 is a section through the print lifter; and

Figure 7 is a perspective view of a modilied Form of printer.

Referring to the drawings more in detail, the. numeral 1 designates the stand or frame of the printer, to the top 2 of which is secured the arm or support 3 for the -cylinder 4. In the cylinder 4 is located the piston 5 and piston rod 6 in the usual manner. The crosshead 7 is secured to the lower end of rod 6, and is slidable'on the rods 8 which are secured to the upper face ot the lid 9. Springs 10 surround the rods 8 and of course are interposed between the crosshead -7 and the lid or platen 9. The. lower .face of the lid 9 carries a felt pad 11 which makes a softand even contact between tlie sensitized paper and the negative,

wheat-he platen 9 is. down in its lower or printing position.

A tank 12 is supported in vthe lower portion of the stand 1, and in this tank is vstored air or other fluid by means of the motor 13 and pump 14. Leading from t-he tank 12 is a pipe 15 which carries the fluid to the valve cylinder 16. Valves 17 in the cylinder 16 are carried by rod 18 and are normally held in the position shown in Fig. 3 by means of the spring 19. Connectdd near the top and bottom of the valve cylinder .16 are the conduits or pipes 2() and 21 leading to the top and bottom respectively of the cylinder .4. By moving the valve 17, by pressure applied through the handor any other part of the operator to its lower position the operating fluid is admitted to thetop of cylinder 4 and lowers the lid 9, while on releasing the valve the spring 19 moves the same to its normal position shown in Fig. 3 and admits the fluidV to the lower portion of cylinder 4 and raises the platen 9 to its clearance position. When the valve l17 is in the position shownv in Fig. 3, the

crosshead with an extension guide arm 22,

which is notched at'23 so as to straddle and slide on the bracket arm 3. Attached to the arm 22 is a libre insulator 24 which carries a contact screw l25. makes connection across the switch bars 26 which are mounted on the fibre insulator 27. The switch bars 26 are in circuit with the lamps in lamp box 28 which is supported -on frame 1 under the top 2 thereof the latter comprising the printing panel customary in The lcontact 25 I this art. The switches 29 are connected in series with the switch bars 26and provide means whereby one or more of the lamps may be used as required.

For the purpose of presenting the print in proper position Vfor easy removal from the machine, I have rovided the vacuum cup 30 mounted on t ie lower end of rod 31. This rod 3l is positioned inthe cylinder 32 which is carried by the lid 9.A A spring 33 in cylinder 32 holds rod 31 and 'vacuum cup 30 normally in the position shown in Fig. 6. As the lid is lowered the spring 33 is compressed and the vacuum cup pressed against the sensitized paper.- On raising the lid 9 the cup picks up the print and the spring 33 moves the cup downward relatively to the lid and thereby presents the print for removal.

A -mask 34 is provided for regulating the size of the print. This mask is fastened to the inside of the frame 1 which' exposes only the leaves of the mask, which latter designate the size of print for which they are adjustable. The mask is operated by means of the knobs 35. A knob 36 is provided for the purpose of tilting the bottom (not shown) of the lamp box to which the lamp sockets are attached, for, the purpose of brin ing the lamps nearer to'certain portions o the negative.

A numberin machine 37 is operated by the crosshead on each downward movement of the lid 9.

In the modied form shown in Fig. 7 the same reference numerals are used to design-ate parts which are the same as those already described in connection with the foregoing embodiment of the invention. In this 40 form the crosshead 74 is guided in the frame members 40, and instead f being operated by Huid pressure is operated by means of a' pressure is operated by means of a treadle 4l toA which isconnected by means of cross-rod 42 the upright connecting rods 43. Between the nuts 44 on the upper ends of rods 43 and the crosshead 7 are interposed the springs 45. Weights 46 are also connected to treadle 4i through chains 47 59 and the cross-rod 4 2. ,By means of 'the weights 46 the treadle 41 is raised and likewise the lid 9 when the foot of the operator is removed from the treadle. A frame screen 48 operablel by knob 49 is provided for dimming the lights .when necessary. This is done by means of sheets of tissue paper laid upon the screen 48.

Numeral 50 indicates a switch for operating the pilot light used in connection with the-,large types of machines.

In' accordance with the patent statutes I have described what I now believe to be the best embodiment of the invention, but I do not wish tobe understood thereby as limiting .myself or the scope of the invention, as

many changes and modifications may be made without de arting from the spirit of the invention, an all such I aim to include in the scope of the appended claims.
